Procedure: In the same apparatus and procedure as Example 1 above, 1.0 g (3.8 mmol) of triphenylphosphine, 6.21 g (38.0 mmol) of (chloromethyl)dimethylchlorosilane, and 27.5 g (190.0 mmol) of trichlorosilane were reacted at 150° C. for 12 hrs. The resulting mixture was distilled to give 5.8 g of 1,1,1,3-tetrachloro-3-methyl-1,3-disilabutane (bp; 169-170° C., yield; 58%) and 1.2 g of 1,1,3-trichloro-3-methyl-1,3-disilabutane (bp; 153-155° C., yield; 8%). The resulting mixture was distilled

Procedure: A stirrer was added to a 250 ml, round bottomed flask, which was equipped with a bubbling column linked to a dry ice/aceton condenser and a chlorine gas cylinder. To the flask were added 100 g (0.41 mole) of 1,1,1,3-tetrachloro-3-methyl-1,3-disilabutane and 1 g of a reaction initiator, azobisisobutyronitrile, using carbon tetrachloride as a solvent. The obtained mixture was photoreacted for 5 hrs using a sun lamp, while bubbling chlorine gas and refluxing carbon tetrachloride. After confirming the degree of the reaction process by gas chromatography, the reaction mixture was distilled under vacuum to obtain 38 g of 1,1,1,3,4-pentachloro-3-methyl-1,3-disilabutane. A stirrer was added to a 250 ml, round bottomed flask, which was equipped with a bubbling column linked to a dry ice/aceton condenser while bubbling chlorine gas refluxing carbon tetrachloride the reaction mixture was distilled under vacuum

Procedure: In the same apparatus and procedure as Example 1 above, 0.27 g (1.5 mmol) of tetrabutylphosphonium chloride, 2.15 g (15.0 mmol) of (chloromethyl)dimethylchlorosilane, and 6.10 g (45.0 mmol) of trichlorosilane were reacted at 150° C. for 10 hrs. The resulting mixture was distilled to give 2.18 g of 1,1,1,3-tetrachloro-3-methyl-1,3-disilabutane (yield; 60%). The resulting mixture was distilled
